To @ZZ whom it may concern.-

Be it `known that I, LEANDER H. WEAVER, of Hudson, in the .county of Columbia and State of New York, have invented a new and Improved Sliding Door,of which the following is a full, clear, and exactdescription.

My invention relates to improvements in doors, and particularly to, house doors; and the object of my invention is to` produce a simple form of collapsible and extensible door, which may be used as a substitute for the ordinary swinging or `laterally sliding doors, and which, when opened, isout of sight, the door collapsing as it is opened and lying in a suitable case above the door opening.

o. A further object of my invention is to con struct thef door and its containing case in such a way that it may be put up without the use of nails and may be very easily operated to open or close it. l.

To these ends my invention consists of certain features of construction and combinations of parts, which will be hereinafter describedand claimed. Y

Reference is to be had to the accompanying drawings, forming` a part of this specication; in which similar figures of reference indicate corresponding parts in all the views.

Figure l is a broken front elevation, `partly in section, of the door embodying my invention. Fig. 2 is a vertical section on the line '2-2 of Fig. 1, with the door closed; Fig. 3

is a similar section with the door open. Fig. 4 is a broken sectional plan on the line 4-4 of Fig. l. Fig. 5 is a broken vertical section of the upper` portion of the door and casing. Fig. 6 is a broken'sectional view, showing the manner in which the casing is fastened to the doorj amb ,and Fig. 7 is a detail sectional view, showing particularlythe means of pullt ing down the door.

grooves14 in the cornice, and cross pieces or trimmings 15 at the lower ends of the panels, these being fastened` to the moldings 11 by means of slide bolts 16 which have knobs 17 thereon working in slots 18 on the inner sides lof the pieces 15, see Fig. 6,7so that to operate the bolts, one reaches his hand up into the casing and grasps a knob, but to do this the doorjmust be raised somewhat, as shown` in 1 Fig. 5, so` that the `top of the upper door secvtion will clear the slide bolt.

The casing 12 is open at the bottom, butits sides are beveled and contracted opposite the opening, as shown at 19 in Figs. 2 and5, so

'as to engage and support the top plate 20 01:'` i

the upper door section 21, the top plate llaving its side edges shaped to lit the parts 19 of the casing.y The door maybe finished in any desired style, may be of any reasonable size g and may be composed of any necessary nurn-` ber of telescoping sections, although three is the number most conveniently used. The upper section 21 is single and itterminates at its lower edge in a foot 22 which lits in. the

contracted upper end 23 of the second section 24 of the door, this section being double, as shown clearly in Figs. 2 and 5, so that` the single section 2l may slide into it, or rathervit may slide over thesection 21. 't

The section 24 has at the bottom a foot 25, which lits in the contracted upper end 26 of the lower door section 27, which section is also double or hollow so that it may slide over the section 24, but the lower section 27- is closed at thebottom, as shown at 28, and has within it at the bottom a packing 29 of rubber or other sound-deadening material. The bottom-of the section 24 is closed by an iron 30 which serves as a brace to prevent. the collapsing of the section.

Projecting from opposite ends of the section 27 are lugs 3l` to which are secured cords and over pulleys 33 in the jambs 10, and the upper ends of the cords are secured to weights 34 which hangin pockets 35 in the door frame, and the heft of these weights is sufficient to rather more than counterbalance the two lower door sections, so that when the door is released at the bottom, the two lower sections i will be raised, the lower one closing over the next one above it, but to raise the door to its full`height it is then necessary to push up# ward slightly o`n` it. Y Y n The upper section 2l of the door has attached to it, von opposite ends, cords 36 which run over pulleys 37 in the jambs l0 and are attached to weights 38 which, in connection with the weights 34, balance the door. The pulleys 37 are larger than the pulleys 33 so that the weights 38 Vwill not interfere with the weights 34.

The door is pulled up, as specified, by the r, the samebeing composed of a series of rectaction of the weights, and to enable the door to be conveniently pulled down,- the middle section is provided with a bail 39 of sti Inaterial which extends down into the section 27, and to this bail is attached acor'd 40 which extends downward through the bottoni of the section 27, so that by grasping the ycord and pulling it down, the door is pulled down.,- and if desired the door may be provided on its exterior` vwith any suitable handheld lto assist in its easy manipulation. 'On the bottom of the door is a keeper plate 41 which,

f when thedoor is closed, goes through a hole 42 in the iioor and engages a slidek bolt 42a which works in a suitable guide 43 and which is ot the ordinary spring kind, so that it automatically engages the cat'ch.- f I l The bolt 42a is pulled back by means of the connectingrod 44 which is connected with a lever 45 fulcrumed, 'as shown at 46, beneath the floor, and the outer en d of this lever is connected with a vertical rod 47 which eX- tends upward through the tloor and into the door frame whereit connects'` with a crank 48 on the knob spindle 49 which project'sthrou'gh the door frame at one side of the door and is' provided at its ends with door knobs 50 of the customary kind,and by turning either ofthe Y knobs the rod 47 may be raised so as to pull back the rod 44 and bolt 4,2thus releasing 1 the door which, impelle'd by the weights, imf mediately opens l claim as new and desire to secure by Letters Patent- `l; The collapsible door herein described,

angular panels, which `are adapted to slide vertically one on another, and have their vertical axes coincident, or aligned, as shown and described.

2. As an improved article of manut'acture,-

a slidiugdo'or comprising an upper single section aud aseriesf of doublel sections .below it and connected with it,` the .sectionsbein'g arrangedtoslideone over the other, substantially as. described. 1 i y e 3'. Th'ecomlbinatiou, .with the couuterbalance'd telescoping door, comprising a series of sections as specified, of the bail secured to one of thesectioiis abovev the lower section,

' audaicord securedl to the bail and'extendiug downward throughthebottom of the lower section', substantially as'-y described.

4. The sliding door, comprising an upper f single section having `a foot at its lower edge, a hollow section below it, having its upper end shaped to fit thefoot of a second section,

l the second section having also a foot at its lower edge, and a third section closed at the bottom' andhaving its topps'haped toitit the l foot of the section above it,- subs'tan'tially as l described.
